One officer flying in the helicopter above the scene can be heard on video saying Crutcher looks like a “bad dude.” Tiffany Crutcher, Terence’s twin sister, said “and because he was a big bad dude” he won’t get to make his family proud like he hoped to.

She said it was clear to her that Terence died because of a Tulsa Police officer's "negligence and incompetency and insensitivity."

"I just feel like I'm in a nightmare really. I just want to wake up and this all be over tomorrow,” Tiffany Crutcher said at a press conference Monday. “I lost my brother, my twin brother who was doing nothing wrong, absolutely nothing wrong and I truly believe in accountability."

Tulsa police released the video of the shooting in an effort to exercise “full transparency and disclosure,” said Officer Tuell, a spokesman for the department. Crutcher suffered a single gunshot wound to the chest, police said. According to the Crutcher family attorneys, Crutcher was having difficulty with his vehicle.

“After watching the video and seeing what actually happened, we asked for the facts, we asked for answers and we clearly got it through the video," said Tiffany.

Police officer Betty Shelby, who is white, fired the deadly shot. On the force since 2011, she has been placed on paid administrative leave while authorities investigate and determine whether charges will be filed.

The U.S. Department of Justice has also opened a probe into the shooting.

Officer Shelby’s lawyer, Scott Wood, said the officer had thought that Mr. Crutcher had a weapon. Wood said Mr. Crutcher had acted erratically, refused to comply with several orders, tried to put his hand in his pocket and reached inside his car window before he was shot, according to The New York Times.

Wood also told the Tulsa World that Shelby has completed drug-recognition expert training and believed Crutcher was acting like he was on PCP. A vial of the drug was later found in his vehicle, according to Fox 23.

The Tulsa Police Chief, Chuck Jordan, called the video “disturbing” at a news conference Monday and said the department will "do the right thing."
